f The'present invention refers to locomotives andsimilarvehicles. Theobjec t of the .in-

r vention is to' provide in a vehicle of the kind Figs. 1 and.2 area sectional side view'and' a crosssectionirespectively of the first embodi- 1 j -ment ofl'a condenser plant ina locomotiveja'ccording to the inventionfand Figs. 3 andz4 I are similar views-of the-second embodiment.

' j 'The condenser plant shownin the drawings described a. condenser plant ofa high efli-m cie'ncy for the eXhaust steam of the main machineryof thelocomotive or the like, such condenser plant also including a re-cooling device for'the cooling liquid of the condenser.

In the accompanying-drawings two 'em-' bodimentsof the invention are illustrated.

isv placed on a separatecarriagewhich is supposed to be coupled wit-ha carriage running in 'front of its left'endandsupporting the .steam boiler of the locomotive and, ifdesired, other aggregates pertaining to the latter.

f The arrow 10 designates the normal running i direction of the locomotive. The main ma- ",chinery of the locomotive is shown to consist Q2 of; a steai'n'turbine 11 disposed on the'same {carriage as the'condenser plant, the power T from said turbine '11 being transmitted to the wheels by means of a toothed-gearing 12.

In Figs. 1 and 2, 14 isa receptacle, filled with water or other cooling .liquidt'o level 18. Below level 18 a number of tubes or pipes 13 extend through the receptacle 14 from a I steam chamber a to a chamber 7). The re ceptacle 14'forms part of a re-cooling device, 135

sistingofclosed elements 15 and 16'placed at I the side of; one another, a plurality of, fans '17 being provided for movingthe air through the air-cooled part. Theffansare situated above thereceptacle, atthe side of one .an-

which'also includes anair-cooled'part con- ;other.

e m 1 the tubes or'pipes 13 located withinthere :ceptacle 14 and surrounded byjthe'water in the receptacle 14, said water consequently we cooling directly the steam as .in a surface con- I denser;-

The air-cooled part 15, 16 is connected by i means'of the ascending pipe v19 with'there ceptacle 14 above its water-level 18. "Thereis led fromth e turbine 11 through Serial No. 155397. Y 1 p cooling ofthe watercontained in therecep-- taclell4is effected by thewater heated there- 'inJbeing pumped by means "of a pump 21".

for its' purpose' to distribute the cooled water mere evenly as'srn'all' drops over the water-f surface in the receptacle thus effecting ay good' mixing of the' jcooled1water with the for driving the pump 21 by means of a transmitting shaft 23 extending fromone of said bevelled gearings 23. To condense the ex haust steam of the turbine 23 there is pro. Y vided a separate jet'condenser'24 receivlngits Water from the distributing pipe 'by means of, apipe 24 The-receptacle 14 aswell as the surface condenser 13 are preferably pro; ,vided with air outlets 25 and 26, and the sur- I face condenser is, as at 27, connected to a condensate-pump in usual manner. The condensate is returned to the steam boiler by means of the feed pump. V

Re-cooling is'effected What We claim as new and desire to secure by Letters Patent of the United States is 1. In locomotives and similar vehicles, an accumulatingreceptacle containing cooling liquid, a plurality "of pipes arranged Within said receptacle below the surface of said cooling liquid, said pipes belng' adapted to work as -a surface condenser, means for bringing the exhaust steam of the main machineryof the locomotlve lnto cont-act wlth said plpes 1n order to condense said steam, an a r-cooled part consisting of closed'eleinents means for oil culating cooling liquid from said receptacle through said air-cooled. part and. a fan for moving the air necessary for cooling through said air-cooled part.

2. In locomotives and similar vehicles, accumulating receptacle containing cooling llquid', a plurality of pipes arranged Within said receptacle below the surface of said cooling liquid, said pipes being adapted to work as .a surface condenser, means for bringing the exhaust steamo-f the. main machinery of the locomotive into contact with said pipes in IOlCleI' to condensesaid steam, an air-cooled part consisting of closed elements, a pump for circulating cooling liquid fronr-saidYre-j ceptacle through said air-cooled part and a plurality of fans situated above said receptacle at the side of one another for moving air throughlsaid air-cooled part.
